STRUCTURE:BODY
Rear Sliding Glass window frame has cracked and allows water to enter the cab of the vehicle. Yes this is available for inspection. The water entering the cab of the vehicle can create mold from moisture build up if left untreated. I was able to have the dealer service center confirm the issue noted in [XXX] but they were unable to repair it as it is outside of warranty. I was able to have an independent 3rd party glass company confirm that it was indeed a manufacturers defect with a cracked housing and not an issue with sealant around the glass itself. No warning lamps or other indications other than water in the back seat of the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
Purchased a brand new from dealer 2019 GMC Sierra 1500 in July 2019. I noticed not long after that time that the back window leaked once in a while when it rained. I live in Phoenix Arizona, so rain is a rare occurance and it is in the back seat area of the truck where I do not sit back there or look back there very often checking for leaks. I mentioned it to the service advisor when I was trying to get a very long running issue with the tire pressure monitors that they would not properly fix. It took nearly 2 years for them to correct that issue, and by the time they fixed that issue, truck was out of warranty and they said they had no record of this problem and they could not fix. I am worried about the water causing mold or rust up under the head liner that would cause me and my family medical issues. Water, metal amd fabric head liners do not mix and there is a water stain on the roof liner that grows every time it rains. This is a medical issue and nobody should have to wonder what is growing above their head inside their vehicle while going to work. I see many online reports of a cracked window frame on these model year trucks, so it seems to be a widespread problem with either their vendor for these windows or the installation process at the factory.

UNKNOWN OR OTHER
Electronic tailgate opened on its own. The tailgate opened while I was either driving down the highway or when it was parked earlier. When I went to park the truck I back the dropped tailgate into a poll because I believed the tailgate was locked closed but it had opened on its own. There is no recall on my vehicle but I believe there has been over 320,000 vehicles like mine that have recalls on them for the same issue. Tailgate opens on its own. I have not had it inspected because they want to charge $179 to run a diagnostic check on it. There were no warnings at all. I've owned the vehicle for around 3 months and there has been one or two time that I questioned if I left the tailgate open or not.

EXTERIOR LIGHTING
Nighttime backing up is to dark to see in the camera. The reverse lights are not bright enough to highlight the area to see correctly. This is a major concern as i almost backed up over my child at night as i could not see them in the camera. Please address with manufacture to resolve the issue. This truck has one piece LED lights that can not be pulled and swapped out with a brighter bulb. would need to replace the entire fixture.
